Product Description
Broadcom 7 nm 400GbE PAM-4 PHY (4:4) with Direct Drive Capability - BCM87842A0KEFBG
The Broadcom BCM87842 is the industry’s highest-performance and lowest-power single-chip 400GbE PAM-4 PHY transceiver capable of driving four lanes of 106-Gb/s PAM-4 at 53 Gbaud, while supporting DR4, FR4 & LR4 optical links. The BCM87842 leverages Broadcom’s market-leading 7-nm PAM-4 PHY transceiver technology platform already proven with the BCM8740X 400Gbe PHY, and it provides a path to accelerating 400G optical module availability.
The BCM87842 leverages Broadcom's market-leading PAM-4 PHY technology platform and delivers a 400G PAM-4 PHY transceiver with a monolithically integrated 56-GBaud PAM-4 laser driver available in 7-nm CMOS. Broadcom's advanced DSP technology and equalization techniques compensate for optical impairments while maintaining the world's lowest power enabling the deployment inside pluggable optical modules and co-packaged optical solutions for EMLs and Silicon Photonics.
